Will Hodgson be booed in Vancouver?

He has played a game in Vancouver after that trade, but it was like a week after and since then we have found out a lot more details about why that trade was made. Will he be booed/cheered or just be treated like any other player?

Depends.
Casual fans probably will not...
But hardcore fans...
And most people from here who can afford to go to games...
Probably will.
Many of them are well-aware of what happened behind the scenes...
And it is hard not to boo him.

Can't see why he'd get any particularly significant response out of the crowd.

I would guess most fans at the Rog are going to be more influenced by a players contribution on the ice than by what their agent said on twitter or what the GM said about their agent or dad or whatever.

On the ice Cody was an effective player for this team for about half a season, so I don't imagine he's going to be the focal point upon returning (again) unless he's a major factor in that game.

I'm sure he'll get some polite applause from the crowd, as hopefully will Christian Ehrhoff who actually had a major impact on the ice as a Canuck.
